- 4 digit number
I am a four-digit number. My thousand period has a first digit, which is thrice the second digit, and the second digit is two more than the third digit. All the rest of the digits are zeros. What number am I? - The whole number
A whole number is increased by seven, and the obtained number is multiplied by five. The result is 45. Find this number. - The Fraction The denominator of a Fraction is greater than the numerator by 4. if 11 is added to the numerator and one subtracted from the denominator, the value of the fraction obtained is 7/3. What is the original fraction?
- Brother age
One brother talks about his younger brother: "2 years ago, I was three times my brother's age. In 3 years, I will be twice as old as my brother." How old is each brother now? - Graph move
When y=2x² has moved 2 units to the left and 3 units upward, what is the graph equation? - Peter brother age
How old is Peter's brother now if he has four times as many in 15 years as he did 15 years ago? - Juice water mixture
The drink was mixed from one hundred percent juice and water in a ratio of 1.5 liters of juice to 2.5 liters of water. Calculate how many liters of this drink will be created by mixing 1 liter of water and juice in the corresponding ratio. Calculate how m - Classroom commute students
In the classroom, 50% of students come from other districts. One-third of them commute by bus, a fifth by bike, and seven pupils walk. How many students are in the class? - GP sequence

- Members
A geometric sequence with six members has the sum of all six members equal to 63; the sum of the even members (that has an even index) has a value of 42. Find these members. - Five people
Five people can finish painting a wall in 4 hours if only two people are available. How many hours do they have to work to finish the same job? - Peter's rectangle
Peter had a rectangle 2 cm wide and of unknown length. The line had a 2 cm rectangle whose length was equal to the perimeter of Peter's rectangle. When they put the rectangles together with their widths, they got a new rectangle with a circumference of 63 - Jointly and cube power
If y varies jointly as x and the cube of z and y=16 when x=4 and z=2, find an equation representing this relationship. a. y=xz b. y = 2xz³ c.y = 2kx/z³ d.y = xz³/2 - Three men
If three men can do a job in 8 days, how many men can do the same job in 6 days? - Three dices
What is the probability that the sum of points 14 will be a roll of three dice (B, M, Z)? - Three cottages
141 guests are accommodated in 3 cottages. In the second cottage, there are eight more guests than in the first cottage, and in the third cottage, there are 14 more guests than in the second cottage. Find out how many guests are staying in the first cotta - Line - normal form
What is the equation of the line whose x-intercept is - 3 and y-intercept is -4? Find coefficients A, B, C in normal equation of line: Ax + By = C - One-half
